Losing track on what I've postyed, an adapter is available now for Canon lenses, in April one for Nikon will be available too...MX camera....on sontalpharumours.....

“We saw our product and video in your website! We are so happy about that!! We are now developing the Contax G to Sony NEX adapter with AF function and it is almost finish. We will update the information to you very soon.Some people email us about Nikon G to NEX (AF support) adapter. We will start this project around November(after Contax G to NEX AF adapter) and we think we will finish it before April 2013.”

So much "close" on the horizon. I guess one question now is Nex6 vs. Nex7?? Rumors of Nex7N or the like?

Well my NEX-6 just arrived

I'm trying to decide if I can base my next UW-vamera on NEX. It comes down to that I want a good low-light capable WA option. Preferably rectilinear, rather not fisheye.

From that viewpoint, NEX right now only has one option, 16mm + adapter (UWA or FW), that for example nauticam houses. There are many comments on quality, but a plus is to be able to play with both WA & FE with the same solution.

How usable would you think the new Sony 10-18 f4 would be UW? It would require a completely different port solution and diameter dome I suppose, right?

Cheers

Hi all,

I will (most likely) buy a NEX-7, but the available lenses are of no interest to me for underwater use.
I'm getting a bit desperate, as I'm leaving on a (very) long journey of photo and diving soonish.

Looking at the Nauticam port chart (http://www.nauticam....t/pdf_143_1.pdf), there are some Nikonos to Nex adapter.

I've no experience in Nikonos, but would that be a viable option?
How does Nikonos lenses work, the aperture and focus knobs are directly on the lens IIUC, which is waterproof without a port? (forgive my ignorance, I was not in the water during the Nikonos era .
Would they be alright for an APC-S sensor?

Any input on the combination NEX 7 with Nikonos glass most appreciated!

cheers,
Christian

I use some Nikonos lenses on a micro-four-thirds camera (Olympus EP1) in a one-of-a-kind experimental housing. The EP1 has a higher crop-factor than the NEX cameras, 2.0 instead of 1.6, but it's lower resolution so the pixel size is probably similar.

Here are my opinions:

The 80mm is REALLY hard to use. I usually try it with the Nikonos close-up adapter for supermacro, but the depth of field of a 160mm equivalent lens along with manual focus is problematic, at least for me. I believe that the lens is sharp, I just haven't gotten any supermacro images in focus yet. Here are the closest:

The 28mm lens is OK, maybe a little better with the closeup adapter, but nothing great. This is my best shot with the 28mm:

The 15mm Nikonos lens is the only one I regularly use. It is more than sharp enough for a 12 megapixel sensor on a 2.0 crop factor camera, which is pretty astounding for a lens that age. Here is an example of a shot I took to try to later identify the beaded anemone, which shows what the 15mm is capable of even on a crop sensor camera:

Personally, I find myself using a modern fisheye lens with autofocus and a dome port more than the Nikonos lenses. As frustrating as autofocus sometimes can be, manual focus is even more frustrating.
